This time I will bring you how to deal with memory leaks in img tags in IE. What are the precautions for dealing with memory leaks in img tags in IE. The following is a practical case. Let’s take a look.
Code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>IMG元素内存泄露测试</title>
<script type="text/javascript" src="jquery-1.7.1.js"></script>
<script type="text/javascript">
$(function () {
var i = 0;
var t;
// img标签方式
function changeImage() {
i++;
var picIndex = i % 20;
$("#imagePath").html("images/" + picIndex + ".jpg");
$("#p").append("<img width='100' height='100' src='images/" + picIndex + ".jpg' />");
};
function end() {
clearInterval(t);
$("#p").find("img").each(function () {
$(this).attr("src", "");
$(this).remove();
});
CollectGarbage();
}
t = window.setInterval(changeImage, 200);
window.setTimeout(end, 5000);
});
</script>
</head>
<body>
<label id="imagePath"></label>
<!-- 使用img标签，不改变图片大小，不会发生内存泄漏。 -->
<p id="p">
</p>
</body>
</html>Release the js code that img takes up memory:
$("#p").find("img").each(function () {
$(this).attr("src", "");
$(this).remove();
});
